Any use of abs?

[rum]

I dont know about abs, its seems as if the only real reason to work on them is if your "skinny" or low body fat...So if youyr a bit bigger would doing ab workouts even do anything?
I know your abs get stronger but is there any different appearance?

a strong midsection helps your squats and bench, and most other power exercises. But they are trained through power exercises also, so you don't need to supplement them too much.

Stronger abs can lead to less lower back problems as well.
